Usefulness of a Cook® airway exchange catheter in laryngeal mask airway-guided fiberoptic intubation in a neonate with Pierre Robin syndrome -A case report-.
The case of a 33-day-old boy with Pierre Robin syndrome using a Cook® airway exchange catheter in laryngeal mask airway-guided fiberoptic intubation is presented. After induction with sevoflurane, classical reusable laryngeal mask airway (LMA) #1 was inserted and ultrathin fiberoptic bronchoscope (FOB) was passed through. ⋯ After successful intubation, the Cook® airway exchange catheter was placed in the midtrachea through the lumen of the endotracheal tube. Even though the tracheal tube was accidentally displaced out of the trachea during LMA removal, the endotracheal tube could be easily railroaded over the airway exchange catheter.

Interruption of bispectral index monitoring by nerve integrity monitoring during tympanoplasty -A case report-.
We report that intraoperative NIM-2 monitoring devices can interfere with bispectral index monitoring. A 45-year-old male with chronic otits media underwent tympanolasty under general anesthesia with NIM-2 monitoring and bispectral index monitoring at our institution. And then, bispectral index monitoring was severely interrupted by facial nerve monitoring.

Vasovagal cardiac arrest during spinal anesthesia for Cesarean section -A case report-.
The vasovagal response is characterized by an inappropriate combination of bradycardia and paradoxical vasodilation. During a general or neuraxial anesthesia-induced sympathectomy, a sudden vagal activation and/or an acute reduction in sympathetic tone can cause serious vasovagal responses. Neuraxial anesthesia for Cesarean section may trigger vasovagal response, due to multiple risk factors; high neuraxial block, sudden hemorrhage, aortocarval compression, peritoneal manipulation, and emotional stress. ⋯ Immediately after the placental expulsion, a sudden severe bradycardia, followed by a cardiac arrest occurred. The patient fully recovered after prompt cardiopulmonary resuscitation with chest compression, manual ventilation with oxygen, rapid injection of epinephrine and hydration. This case illustrates a serious potential risk of vasovagal response superimposed on neuraxial anesthesia, during a Cesarean section, especially during placental expulsion.

Rocuronium-induced withdrawal movement: influence of ketorolac or a combination of lidocaine and ketorolac pretreatment.
Pain on injection of rocuronium is a common clinical problem. We compared the efficacy of lidocaine, ketorolac, and the 2 in combination as pretreatment for the prevention of rocuronium-induced withdrawal movement. ⋯ Ketorolac pretreatment had an effect comparable to that of lidocaine in attenuating rocuronium-induced withdrawal movements and the lidocaine/ketorolac combination pretreatment, compared with lidocaine or ketorolac alone, effectively reduced withdrawal movements during rocuronium injection.

Sugammadex is a modified gamma-cyclodextrin which is showing favorable outcomes regarding reversal of neuromuscular blockade, especially by rocuronium. It is designed to encapsulate rocuronium and being considered a new class of drugs as selective relaxant binding agents. It has given countless benefits to the patients at risk of incomplete or delayed recovery after neuromuscular block and has renown for another milestone in anesthesia practice. ⋯ Acceptable profiles are brought to light telling safety of sugammadex. However, some questions related to the twitch characteristics those resembled succinylcholine when reversal, the application for rocuronium anaphylaxis, and the hypersensitivity or anaphylaxis to sugammadex remain and are need of further investigation. It is imperative that potential problems that we need attention may include the patient's history of pulmonary disease and allergic disease for using sugammadex.
